I'm still fraught with getting caught up after being away for two weeks, but here's something I can get out quickly which I saw pop up in my Google alerts a few days back.
Here's an article worth reading by William Faloon in Life Extension Magazine. Key excerpts:
For instance, a study published in June 2008 showed that men with low vitamin D levels suffer 2.42 times more heart attacks. Now look what this means in actual body counts. […]
To put the number of lives saved in context, tens of millions of dollars are being spent to advertise that Lipitor® reduces heart attacks by 37%. This is certainly a decent number, but not when compared with how many lives could be saved by vitamin D. According to the latest study, men with the higher vitamin D levels had a 142% reduction in heart attacks. […]
Vitamin D-deficient women, for example, have a 253% increased risk of colon cancer. […]
A study published in January 2008 showed that women with the lowest level of vitamin D were at a 222% increased risk for developing breast cancer. […]
Men with higher levels of vitamin D have a 52% reduced incidence of prostate cancer. […]
During winter months in Canada, for instance, an estimated 97% of the population is vitamin D-deficient. […]
In a study published in September 2008, blood indicators of vitamin D status were measured in 3,316 patients with suspected coronary artery disease. The subjects were followed for 7.75 years. For every small decrease in blood indicators of vitamin D status, there was a startling 86% increase in the number of fatal strokes. […]
According to John Jacob Cannell, MD, founder of the non-profit Vitamin D Counsel: "Current research indicates vitamin D deficiency plays a role in causing seventeen varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, and periodontal disease."
Dr. William Davis also remarked on this article (with additional info). Here's the Carlson supplements I take, each gelcap being the size of a raindrop. Currently, I take three per day, 6,000 IU. A bottle of 120 of those babies, a 40-day supply, runs under $10. Under $10!
Let's put it another way. In terms of epidemiological correlation, you can reduce your risk of cancer 30% by stopping smoking if you smoke. But if you're vitamin D deficient, you can reduce your risk of cancer by 50% just getting your level above 30 (serum 25 (OH) D, ng/mL), and getting it above 60 virtually eliminates risk (in terms of associative correlation, i.e., epidemiological risk factors). Bottom line? If you have vitamin D levels below 30, you're at a higher risk of cancer than for a smoker with vitamin D levels above 30. More here, particularly the last two graphs.
